Definitions

  • the invention relates to a method for regulating a device for a stratified ventilation in a space to be ventilated, wherein a layer boundary forms between a first geodesic lower air layer and a second geodesic upper air layer, according to the preamble of claim 1, and a device for stratification ventilation according to the method the preamble of claim 10.
  • the supply air is introduced via air outlets near the floor in the room to be ventilated.
  • Thermal convection flows develop above thermal sources in the room, such as production facilities, mechanical equipment or people in the room.
  • the room air heated by the thermal sources rises due to their lower density in the upper spatial area, and so also transports pollutants from the occupied area of the people in the room in an overlying this air layer.
  • a layer boundary thus forms between a geodetically lower first air layer and a geodetically upper second air layer.
  • the height of the layer boundary above the floor level of the space to be ventilated depends essentially on the amount of air introduced into the first lower air layer and the amount of air removed from the upper second air layer. Ideally, the amount of air supplied and discharged, ie the supply air volumes and the Exhaust air volumes, adjusted so that the layer boundary stabilizes at a height of, for example, 2.5 meters above the floor level of the room. This ensures, on the one hand, that the pollutant load in the production area in which people are present is significantly reduced, while at the same time minimizing the energy requirement for the operation of the ventilation systems. Another influence on the ambient air conditions that occur when a device for stratification ventilation operates, in particular the dynamics of the convection flows, is the temperature of the supply air.
  • the amount of air supplied is usually adjusted to a representative stationary operating state of production. Since there is no automatic adaptation to the ongoing production process, for example due to production or staff breaks or shift changes, the height of the shift boundary shifts to energy-unfavorable areas that are not required by man and machine.
  • the height of the layer boundary is also determined by the arrangement of the thermal sources within the space to be ventilated, as well as by the design and arrangement of the ventilation device.

  • the method according to the invention ensures optimum operation of the device for stratified ventilation, which reacts flexibly to changing ambient air conditions, for example due to changed production conditions. By adjusting, for example, the ventilation performance during breaks in production, the energy requirement can be reduced by lower fan speeds and the associated lower required cooling capacities of the supply air volume flow.
